Highfield Resources announced the results of an independent technical review undertaken by SRK Consulting (UK) Limited of the updated Ore Reserve estimate ("ORE") and Exploration Target prepared for its Muga-Vipasca Potash Project. Highfield together with IGAN, a Spanish mining consultant company, recently completed a detailed mine plan for the Project with revised production and backfilling schedules. The mine plan provides detailed design of access development to the production zones where the shallow dipping seams, which cover most of the initial years of production, will be mined. The updated ORE takes into account the conditions and constraints resulting from the Environmental Permit ("DIA") and Mining Concession (awarded 1 July 2021), primarily related to exclusion zones. The updated ORE also considers the most recent MRE which now includes the Vipasca Licence area where seven additional drillholes have been completed since the previous estimate was produced. In addition to the updated ORE, the Company has also produced an updated Exploration Target which encompasses both the Vipasca Licence area and the Muga Sur Licence area and which has also been reviewed by SRK.
